The'uniznre of my invention cons1sts- First, in the combination with thepattern-chain,

' ho'n'ztmtnl indictor-leveis, and double hooks'oi vhorizontal travelersor slides, se Wiil'be ierenfterexpinincd. Second, in the-pecnliaiiy-constz1uoted indicatorle vers, hereafter described.,

. 'Third,'in thecombinntion-wit-ln the horizontal slides l ortravelers,supported above the harnessinmes, of

the cords or wires,s`hems, andbottom harness-levers, as will behereafter set forth.

In the dra\ving-. A ik me thcsidepieces of the loom-frame, securedtogether by the cross-bars or stays 42li and the breastbezunC.

To tiret-ops or tne side pieces A Anregsecured two top cross4pi'eces D D,which project beyond the lower vpartei the froment one side, as shownat E E.

Upon the outer ends E- E oi' the top pieces D D are supported thepattern-chain F :md its shaft F. l The neer ends of' the horizontalindicator-levels G 'rest on the pattern-chain, as shown in the drawing,said levers being supported on the cross-bar a, which l is sustained bystands b, fastened to the tops of the .projecting ends E E of thecross-pieces D I).

The indicator levers G are provided with under slots c, whereby they canbe easily and quickly removed, for repairs or otherwise.

-Thefront ends of the parts G' of the indicator-levers' G are made .withslotsor recesses 'to receive the rear ends of the ngers d, which nresecurely fastened in said recesses. to the parts G', by. screws, pins,or otherwise.

The tingen-parts d of theindicnioilevcrs extend forivan'through slots orholes in the upright projec iiniSDQi-be front ends of the double hooksH.

The double hooks ere pivoted topojecions 1 onl the `upper edges of thehorizontelslides or travelers i,

which slide upon and are supported by the crossherey l I. .When saidbals are mede thin, they should be held in pince ny means of ginds-pinsor lugs .2 on the upper sidesv ci ;tho supporting-bals l'.

'.ihe horizontal, slides or travelers I are provided with hooks at eachend, for the purpose' of attaching the cords or wires 3' and l, Thecords' 4, passing over sheaves or rolls '5, nre connected to the uppersides of Y the liarness-i`mrnes J,while the cords 3 pass overrolls orshens 6, tiren' down, and are hooked upon the' outer ends ofihennderharness-leveled', es fully in. dicnted in the drawing.

". lfhe nnder levers J' nre hinged or pivoted to e proper l support,upon which thcy'ni'e free intimate, their inner ends beingsecured to theunder sides nl the hn1'nessi'rnrnes by ineens of cords/i2.

The top pieces-D are cast with elevations nnd are pinned to receive andsnpportihe horinontnlhnrnesshars or .knives KK', the enter edges o'which are manie with under bevels, es indicated infdrewing, tlg. 3.

The hnmessiers or knives K are held down in place, as' lthey sliders`and from erich other, by ineens of detachn'ble holding or guide-piecesL, fastened, b v vtirent-is of screws or bolts 8, to the npper edges ofthe projcc tions j'.v

. To' theens of the harness bars or knives K are hinged'or swiveied theinner 'ends'oiihe side arms or connections M, thecnter ends of snid nrmsor connections being hinged-or swiveled to the lowerv ports oi' therocker-plntes or arms N N, on the ends of rockerslmft N', which issupported and rocks in bearings 9, a secured to the upper edges ci' thcprojecting ends E E of the top pieces D'D.

lo the ends of the here or knives K nre hinged or swive'icd the (innerends of the curved side arms or conu nectionsv O O, the renr ends ofsaid connections being hingen or swiveled to thc npper pruts of therockerplntes or arms N.

To one end oi' the clank-shaft P, which works the iny'in the ordinarymanner, is secured a, crank, P', which is connected to one of therocker-pistes N, by means of accnnecting-rod, a. hinged wrist or jointbeing used at each end of said connection, for the pur-V pose ofpreventing binding.

Upon the front end of the pntteruchnin shaft li" is fastened a.stnr\vl1cel, 10, und inside of that a pnwi holder, 11,'to theinside ofwhich is secured thc paw! 12, (which 'trikes into the ratchet-wheel 13,and thereby moves the pattern-.chain and its sha-fn when the 'loom is inoneintien.

star-wheel 10, to prevent thc chain mechanism from being thrown out ofposition` only when moved by the ratchet 13, at which' times the upperend ofiever R is thrown back, the spring m yieldingfo'r that purpose.

I 'The lowerend of paul-helder llis counectedto one each other, while,at-the same time, the pattern-chain.

F will have an intermittent rotaryl motion imparted to it by .means of.the action of .pawl 12 upon ythel ratchet-wheel 13. f

The indicator-levers Gare suspended so that their 1nl'eigght c auscstheir fingers d to be e levated,as shownv in 'blue lines, fig. 3, whentheir 'outerends are nobele-f rated by the pattern-chain, as showninidotted lines4 in' sanie figure, while the doublehooks H are so con'-structed that their outer ends will be elevated, unless forced down bythe depression' of fingers d.

ends of the double l,hooks Hfwill be caught by the harness-har or knifeK, in the formation of 'each sh'ed,l except those whose outer ends, aredepressed by the fingers' d, whichwill be caught by theharness-operating knife or har Ki. Y -It will be. seen that-,' when. theharnessslides orl knivesK K are 'moved toward each other, they-wiltlstrike the projections 1, and thus move the slides I and. double' hooksvH, soa-s to even the?` harnesses J, slides I and doublehooks H beingalso evened at the same time, and which operation takes place at each'beat of the lay. Simultaneously with yeach evening operation. thepattern-chain isgrnoved seas to`-clange the position of the indicatiif'g-levers G, -to"cau'se' the' desired. number ofharnesses 4tobe raisedordepressemfas the case may be, hy'thefaction of the bars or knives KK',

the pattern-chain F, being' used in the usual; manner.

The number of harnesses te .he raised will be indicated bythe' number oflevers' G which Ahave their outer ends elevated; all the other harnessesn'ill'rbe depressed.' 'i

'It will be seen, from the foregoing description, that my indicatingmechanism is not' only simple in construction, but is very effectual andaccurate.. not depending' upon springs; nor is it. liable 4toany-derange; meut by reason of the springing or yieidingof tensionswires `or connections.' A

:It-willalso bsobserved that the indicating-.leversare not liable toinjury or breakage by any accidental deran gement of the patternfchain,whereby` their outer parts Gto be raised bodily.

In the employment of the various indicating moch- -anisms used infaucylooms, the double hooks are more or less liable to slip from orbecome detached from the bars or. knives by which they are moved duringthe operation of forming the sheds, thereby causing imperfect weaving.'

To remedy such objections, resort has been had to .springs and othersimilar devices.

In theluse of my harness-operating and' indicating mechanism, theforegoing objections are obvia-ted by .the indicating-levers themselves.The fingers d tend to hold the hooks 1i upon harness-operating bar orknife K -when the outer ends of lines, fig. 3, and uponharness-`operating bar o r knife K when the outerends of .theindicating-levers'- are elevated, assbown in dotted'lines, same' figure.

By arranging the pattern-chain, indicating mechanism,- and mechanism forevening and 'spreading the As a consequence of 'this construction, -allthe inner Aharnesses upon the extended ends of Vthe cross-piecesanddescribed, the use of long arms and' levers-.and complicatedmechanism heretofore 'in Luse is ohviated, while the putter-chain,indicating and harnessvop'eratingincchanism can be more convenient-lyreached for repairsand other purposes. f Then, again, by'my arrangementand construction a lesser amount of metal is 'required than hasheretofore in which the mechanism s-axranged and combined.

Having described. my improvements iu fancy-looms, What.lclairnlthereiuas new and of .my invention,
